Timing of Furlow Palatoplasty for Patients With Submucous Cleft Palate.

Abstract

Submucous cleft palate (SMCP) is the most common form of cleft involving the posterior palate, resulting in variable degrees of velar dysfunction and speech disturbance. Although early surgical intervention is indicated for patients with true cleft palate, the indications for palatoplasty and timing of surgical intervention for patients with SMCP remain controversial. Twenty-nine patients with SMCP were retrospectively reviewed. Patients treated with Furlow palatoplasty were dichotomized based on patient age at the time of surgical correction into early speech development and late speech development. Primary outcome measures included standardized assessments of hypernasal resonance and quantitative pre- and postoperative nasometry scores. Patients managed nonoperatively were included for comparison of early and late speech outcomes. Both early and late groups demonstrated improvement in qualitative assessment of hypernasal resonance following Furlow palatoplasty. Early and late groups also had significant improvement in pre- to postoperative nasometry scores from 7.4 to 2.3 SD from norm ( P = .01) and 6.0 to 3.6 SD from norm ( P = .02), respectively. There was no difference in postoperative nasometry scores between early and late groups, 2.3 and 3.6 SD ( P = .12). Furlow palatoplasty significantly improves the degree of hypernasality in patients with SMCP based on pre- and postoperative nasometry scores and on qualitative assessment of hypernasality. There were no differences in speech outcomes based on early compared with late operative intervention. Therefore, early palatal repair is not obligatory for optimal speech outcomes in children with SMCP and palatoplasty should be deferred until the emergence of overt velopharyngeal insufficiency.
